As of this writing (July 2021), we are using:
- Java 8 on all of our systems for all options that run on Minecraft 1.16.5 or older.
- Java 11 for Mohist 1.16.5.
- Java 16 for options running Minecraft 1.17 and newer.
You can change the Java version you are using if/when needed by renaming your server jar accordingly and using the relevant Custom Server JAR option on the jar list:
- Java 8 - custom_server.jar
- Java 11 - custom_server_j11.jar
- Java 16 - custom_server_j16.jar
